Anti-slip shoe sole

ABSTRACT

The anti-slip sport shoe sole (1) surface has an anti-slip surface (2) with small pieces of hard material (3) that are bonded during the manufacture of the sport shoe with the flexible surface of the sport shoe sole (1). The small pieces of hard material (3) come into contact with the ground upon contact of the sport shoe sole (1) with the ground. The anti-slip sport shoe sole is intended for sports disciplines on soft stadium surfaces.

TECHNICAL AREA

The sport shoe with an anti-slip sport shoe sole made during themanufacture of the sport shoe is intended for sports disciplines on softstadium surfaces.

CURRENT STATUS

The anti-slip character of the shoe soles is to date a long-termunresolved problem. Soles with spikes are used for sports disciplines,which greatly burden and damage the Achilles and other tendons in thelegs.

The document WO 03/037128 A1 discloses the subsequent creation of ananti-slip surface on the common footwear using different adhesives andparticulate material. The subsequent creation of the part anti-slipsurface on the shoe can be repeated more times. The modificationfootwear is used on slippery ground as ice, packed snow or slimyterrain. As disclosed on cited page 11, para 4 and page 15, para 1, thehard material is encapsulated not in the sole of the shoe, but in theadhesive which is applied (bonded) onto the sole of the shoe.

Other documents, such as JP 2008 000520 A, KR 2003 0059752 A, U.S. Pat.No. 2,732,065, or U.S. Pat. No. 6,055,748, describe subsequent creationthe part anti-slip surface on common footwear with using differentadhesive anti-slip tape and parts. Yet other documents, such as RU 109377 U1, or U.S. Pat. No. 4,702,021, use the removable non-slip sole ortape.

All cited documents relate to modification of common footwear used onslippery ground as ice, packed snow or slimy terrain, none of themsolves the problem of alternative sport shoes not using regular spikes.

Advantages of the Invention

The new anti-slip sport shoe sole has an anti-slip effect on softstadium surfaces. The anti-slip sport shoe sole is the permanentcomponent of the sport shoe and has perfect quality and long life timeas the sport shoe.

Essence of the Invention

The sport shoe sole 1 surface, which is in contact with the ground, hasan anti-slip surface 2, which has small pieces of hard material 3 fixedduring the manufacture of the sport shoe to the flexible part of thesurface of the sport shoe sole 1, such that the small pieces of hardmaterial 3 are permanently bonded with the flexible part of theanti-slip surface 2 of the sport shoe sole 1 and the outer parts of thesmall pieces of hard material 3 protrude from the surface of theflexible part of the anti-slip surface 2 and upon contact of the sportshoe sole 1 with the ground, the small pieces of hard material 3 are incontact with the ground.

In another embodiment, the anti-slip surface 2 of the sport shoe sole 1is a layer of flexible material 4, which is permanently bonded duringthe manufacture of the sport shoe with the sport shoe sole 1. Thesurface of the layer of flexible material 4 has small pieces of hardmaterial 3 bonded with its surface, such that the small pieces of hardmaterial 3 are permanently bonded with the surface of the layer offlexible material 4 and the outer parts of the small pieces of hardmaterial 3 protrude above the surface of the layer of flexible material4.

The layer of flexible material 4 is preferably rubber.

The layer of flexible material 4 is preferably plastic.

The small pieces of hard material 3 are preferably ceramic.

The small pieces of hard material 3 are preferably corundum.

The anti-slip sport shoe sole is made during the manufacture of thesport shoe.
